Amusing little back and forth between siblings and about family. Feels very genuinely adolescent, and I mean that in a good way. It doesn’t directly play at anything bigger or fantastical or mystical—it’s just life, ya know. Good job.
Pretty good story. Is this based on a real incident? It certainly seems real and reminds me of a family story in which we found out that my Great Grandfather was not really our Great Grandfather!
